Abstract
The paper discusses the design considerations associated with the use of the new photodetector structure in the context of a 128 element photodetector array being developed for real-time processing of wide bandwidth signals. This design uses a series-parallel architecture to provide a minimum exposure time of 1 mu s. The photodetector and readout electronics are optimized to provide high sensitivity and response speed for transient signals. Simulation results for the time response to pulse signals and the crosstalk performance are presented. These suggest that the dynamic range exceeds 50 dB for pulses less than 1 mu s in duration.
